ACETYLENIl-GAS GENERATOR.

Specification of Letters Patent. Application filed June 13, 1910. Serial No. 566,583.

To all whom 'it may concern:

Be it known that we, WILLIAM. W. Toner and ALFRED J. TOBEY, citizens of the United States, residing at Iola, in the county of Allen and State of Kansas, have'invented certain new and useful Improvements in Acetylene-Gas Generators; andwe'do declare the following to. be a" full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use thesame, reference being had to the accompanymg drawings,

and to the letters and figurr's f reference marked thereon, which form a part of th s specification.

Our invention relates to acetylene gas gen-'1 erators, and has for its object to simplify the construction'with a view to facilitating its end caps is a rod the ends of which pro application to an automobile running board or frame, and to provide a gas jacket; for the water chamber to obviate freezing,- and to provide an improved as filter. Other objects: of t e invention are apparent from the descriptionand from the drawings, in which:-'

Figure I is a longitudinalsection of a generator constructed iaccording to our in vention. Fig II is a cross section on the seated against thev shoulder 6 and into the groove 8. w

. 12 designates a. cylinder'which fits snugly within 'the' keeperfianges 7 and 10 of the re-' spective end caps and abuts against the packing rings 11 to form an air tight joint when the device is fully assembled. I

Extending through-the aperteres-4 in the ject beyonc'tthe en caps and are threaded to receive the "huts "l4and' 15, which latter are adapted to-screwg o'nithe rods and against the end caps to bind the-parts firmly to gether and lock the "cylinder 12 against its packing rings. I

Mir-designates a cylinder which is seated in the groove 8, againstthe keeper ,flange9,

greater than the water pressure.

in "the cover 34.

and at its other end is seated in a groove 17 of a diaphragm plate 18 which is carried on Patented Dec. 13, 1910.

the rod 13. The late 18 is held firmly in 7 position by a col ar 19 which is rigidly.

mounted on the rod 13. The plate 18, is provided with packing 20 to pro- .vide a tight joint between the plate and cylinder 16.

The end of the 'rod 13 which projects through cap 2, is bored to form avalve stem channel 21, seat 22, and passage wa 23.

Fixed in the passage way 23 is "amtu e24 roove 17, in

having a ball valve 25, at its end, throu h I i which water from the chamber, .formed the. cylinder 16, cap 2, and p1ate 18, may pass into the tube when the gas pressure is Opening into valve stem channel 21 is a tube '26 which extends through the diaphragm plate 18 and almost to the opposite end of the generator and is provided outside of the Water chamber with apertures 27.

v Extendin through the stem channel 21 and ,thIOllll .the nut 15 v is :1 valve stem 28 having a needle point 29 adapted to regulate the opening in the valve seat 22.

We prefer to provide an ordinary stulfing box- 29 on the nut 15 as illustrated.

In the cap 2 is an opening 30 in which is located a'plug 31 having an automatic valve 32, so that the plug may be removed to fill I the chamber with water, and air supplied through the valve 32 when the plug is in place.

In the gas chamberhwhich is formed by' the cylinder 12, cap 1, 1e inside of the water chamber anda part of the cap groove 8, is a carbid can 33 having a lid 34' which is provided with a central aperture that registers with a. central aperture in the can bottom, so that the body may be projected over the rod 13-. Extending throughout the length of the carbid can is a' mesh partition 35 which divides the can into halves, andseparates the charge of carbidto facilitate generation of gas. In one sideof the can is formed a trough 36 for receiving the water tube 27; this troughbeing provided with apertures 37 in its bottom, throughv whlch water from the pipe may trickle into the carbid can and through which the generatcd gas may escape. Gas from the carbid can may alsooescape through pen ig1gs 38 3}) designates a *spring 'wh-ich" is boiled around thefrod 13 .and again llifl fi inner face of cap 1 and the outer face of lid 84 in order to retain the lid in position after the case has been closed.

In the cap 1 is an aperture e0 into which is threaded a plug 41 having a valved channel 42 and valve seat 13; the opening in which is regulated by a needle valve 44:.

45 designates a casing on the inner face of capl which is provided with apertures 46 through which gas from .the gas chamber may pass a packing of asbestos fiber, or the like, being located within the casing to act as a filter for the gas.

\Ve prefer to construct the carbid can of suttieiently less diameter than the interior diameter of the cylinder 12 to provide an annulus 4.7 within which gas may circulate.

The cylinder 16 and diaph'agm plate 18 are adapted to provide an annulus 18 around the water chamber, within which the gas may circulate to provide a gas packing and obviate freezing of the water in thischamber during extremely cold weather.

Surroundin the cylinder 12 are jointed bands 49, havmg lugs 50 in which bolts 51 are pivoted and having 52 into which the bolts may pass to be secured thereto by wing nuts 53. The bandsdQ are also provided with feet 54, by which they may be secured to the running board or frame of an automobne .or other vehicle.

We prefer to provide the device with gages 55 and 56 for indicating the gas and water pressure respectively. 4

To install the generator the bands 49 are secured to a convenient port-iolr of the ve hicles, (n t shown) so that the loose portions may be swung away from the fixed port-ion, when it is desired to remove the tank. To charge the tank, the loose band portions are disconnected from the rigid pur tions and swung away from same, so that the tank may be removed. The nut 1+ is unscrewed, the cap 1 removed from thecylinder 12 and the can 2353 taken out of the cyl inder; carbid is then placed in the can and the latter is replaced in the cylinder and the cap again tightened against the end of the cylinder to form a gas tight j|oint. The plug 31 is removed and the water chamber charged, after which the plug may be 'ethe filter and valve plug ll to the lamps, the

latter being connected to the valve plug by a suitable tube, not shown. When a suflicient quantity of gas has been generated, the pressure of gas in the pipe 27 forces the water back through the conduits a) valve 25 which is closed to shut off the supply of water until the gas chamber has been depleted and a new supply is necessary.

It is apparent that when the pressure in the gas chamber gets below the pressure in the water chamber, that the Valve 25 will chamber set into thev groove in said end cap within the maincylinder and setin therefrom to provide an annulus, a, diaphragm plate carried on said rod and having a groove into which the opposite end of said cylindrical water chamber is projected, a carbid cylinder set in from the main cylinder to provide an annulus, a tube havingcommunication with said valve channel and projected through said diaphragm plate, a valve adapted for controlling flow through said valve channel and tube, and separate means for communication with the gas and water chamber, substantially as and for the purpose set forth. r I

2. In an acetylene gas generator, a tank having separate water, carbid and gas chambers, a centrally located rod having threaded ends carrying clamping nuts whereby the parts of the generator are held in position, said rod having a valve channel and seat near one end,- avalve stem inthe valve channel in said rod, a stufiing box formed in said adjacent clamping nut, a check valved connection between said gas and \vaterchamhers. connection between said valve and said carbid chamber. a filler capamd air charging valve for said water chamber, and an outlet valve for said gas chamber. substantially as and for the purpose set forth. In testimony whereof we allix' our signatures in presence of two witnesses. I
